Thanks, yes, that should work well for 2D. I actually just thought of a
corner case (pun intended) in 3D. It is possible for a cell's vertex to be
on a boundary, without any of its neighbour actually have a boundary face.
Imagine a 3D cube with a hollow inner cube. The cells directly diagonal to

It seems like I might have to loop over the neighbors of every cell to make
sure that account for all the corners/edges DoFs that might be on a boundary,
but that seems inefficient.
Anyone knows of a better way within deal.II to deal with this?

Hello Jose,
I wish I could help, but I second Wolfgang's question.
Is your code available somewhere? I would be glad to take a look at it and
compare the solutions for the same problems using different formulations. I
would expect that if you fix the issue with boundary conditions (those

Hello everyone,
Sorry to revive this thread, but I have a similar question that follows up
his question. In the case of a distributed grid, there might be
vertices/DoFs on a corner (or even edges in 3D) of a cell.
For example, see attached figure (at the trailing edge of the airfoil in
the sq

Maurice,
Is there any reason that you don't use
DoFTools::make_periodicity_constraints() as shown in
https://www.dealii.org/current/doxygen/deal.II/step_45.html?
Best,

Dear all,
For a project, I try to implement a parallel distributed homogenization
problem with periodic BC. A serial version is already implemented.
The feature of the periodic BC in the serial case is that it is not purely
periodic, but periodic with some offset.
Therefore the periodic bo
Hello all
Let me preface by saying that I am not currently a user of deal.II. In fact
I am currently looking for a finite element code that will suit my needs.
I am looking to solve an inverse finite element problem where the material
is hyperelastic, and some boundary conditions are unknown.
Dear Jose,
While I have not experimented in detail with the step-35 program, we
have done extensive studies on similar problems in
